Ross, previously deputy MD of the technology practice, has been promoted following the departure of Michelle McGlocklin.
At the same time, Kate Steele, who co-leads the agency's pan-EMEA Microsoft relationship, has been promoted to senior director of the technology practice.
Ross said: 'This is an amazing time to be in technology PR. Innovation has never set so many news headlines or shaped our lives in quite the way it’s doing now. The impact of all this innovation across so many industries in such a short amount of time is unprecedented, and it’s thrilling for our team to be at the epicentre.
'We are seeing tremendous opportunity, thinking more horizontally, supporting clients across the commercial spectrum with technology innovation campaigns.’
Growth in areas such as mobile, security, media and entertainment, and industrial technology were highlighted by Ross as areas of focus.
He also pointed to clients becoming ‘increasingly active’ in emerging markets such as North and sub-Sahara Africa, the Middle East and the CIS, adding: ‘Clients expect the same level of service in Cairo as they do in London or Munich, so we have spent time strengthening our capabilities in these regions’
Last week, PRWeek revealed the move by McGlocklin, whose decision follows 20 years with the agency.
